2015 年9月~2016 年12 月河北省部分医院肠道门诊腹泻病例便样本及流行病学相关资料, 采用 RT-PCR 方法检测 诺如病毒并进行数据分析.结果 在1240 样本中, 诺如病毒阳性

58 份, 阳性率为 4.68%;

诺如病毒阳性率 存在地域差异, 邢台地区阳性率最高为 10.08%;

全年均有散发病例但在冬春季节出现明显的发病高峰;

基 因型以 GⅡ型为主(4.28%), GI 型阳性率 0.40%;

易感人群为婴幼儿(0~6 岁)和老年组(66~), 其感染不存在性 别差异.结论 诺如病毒是河北省散发感染性腹泻的重要病原, 应加强对诺如病毒的监测, 并进一步研究其 变异, 为诺如病毒感染的预防和控制提供科学的依据. 关键词: 诺如病毒;

Methods The diarrhea stool samples and epidemiological related data from September

2015 to December

2016 in the intestinal clinic were collected, and norovirus was detected and classified by RT-PCR. Results A total of

58 (4.68%) positive specimens were detected among

1240 sporadic cases of acute diarrhea;

the positive rate of norovirus varied by region, and the highest positive rate of Xingtai was 10.08%. There were sporadic cases throughout the year, but there were obvious peak in winter and spring. The genotype was mainly GⅡtype

2074 食品安全质量检测学报第10 卷(4.28%), GI type positive rate was 0.40%. The susceptible population was infants (0~6) and the elderly group (66~), and there was no difference infection in gender. Conclusion Norovirus is an important pathogen of infections diarrhea in Hebei province. The monitoring of norovirus should be strengthened, and its variation should be further studied to provide a scientific basis for the prevention and control of norovirus infection.
